2 Claims.

The invention relates to valves for use in fluid conducting lines tocontrol the flow therethrough.

It is an object of the invention to provide a valve to be employed withother similar valves r with a connecting member which is adjustable invarious positions.

I also desire to provide a valve which may be employed with a checkvalve so that when the check valve is not in operation the outlet portmay be closed by a manually adjustable valve.

It is a further object of the invention to provide a valve adapted forconnection with other valves or other coupling members whereby thecourse of flow through the valve may be directed in a plurality ofdirections.

In the drawings herewith Fig. l is a central longitudinal sectionthrough a valve assembly illustrating one embodiment of the invention.

Fig. 2 is a similar view partly in elevation and showing a differentcoupling member employed with the valve.

Fig. 3 is a central longitudinal section through two separate valvessecured together for operation to assure a closure through a fluidconducting line.

Fig. 4 is a side view partly in elevation and partly in sectionillustrating the construction of a check valve which may be employedwith the coupling member. v

Fig. 5 is a central longitudinal section through one embodiment of thevalve shown'in combination with a check valve in the outlet port of thevalve body. v

Fig. 6 is an end elevation of the check valve disclosed in Fig. 4.

In carrying out my invention I provide a valve body i, having a valvechamber 2 therein. At

one side of the valve chamber is a laterally pro-' jecting bonnet 3which serves as a support for the valve stem 4. The bonnet is providedwith an interior threaded portion 5 which cooperates with a threadedsection 6 of the valve stem and it will be obvious that this is anordinary rising stem valve connection. I provide a handle I onthe valvewhereby the valve may be rotated to move the valve stem axially of thebonnet. I

There is a lateral port 8 in the valve chamber which is threaded at 9for connection with pipe or other fluid conducting means. In theembodiment shown in Fig. 1 the port is directed at an upward angle fromthe valve chamber but it will be obvious that it may be made directly atright angles to the chamber. 7

There is, a second port which in this embodiment is the outlet portshown at 10. The passage through the port I0 is recessed or countersunkslightly at H to receive a valve seat ring i2.

Said seat ring is reversible and has a beveled face 63 on either side toform a seat for a valve member IA.

The valve I4 is secured to the forward end of the valve stem by clampingthe same between an inner nut IE on the stem and an outer nut it?thereon. The valve member is also adapted to be reversed in position. Ithas lateral seating areas H on either end thereof formed to engage thevalve seat. a

The outlet port I ll is adapted to be connected with a coupling member-I8 having a passage it therethrough for fluid passing to or from thevalve. The coupling member here shown is formed with an annular recess20 therein to engage with the seat ring l2 and it'will be understoodthat there are laterally projecting flanges ii at opposite sides of boththe valve body l and the coupling member I8, as in Figs. 2 and 6. Theselaterally extending flanges have openings therethrough to receive bolts22, thus forming the usual flanged connection between the body and thecoupling member. It will be noted that the coupling is directedlaterally at an angle to the valve seat and in the present instance thethreaded outlet 23 in the coupling member is directed at right angles tothe inlet 9 to the valve chamber 2. In this case I have thus provided anangle valve which directs the fluid at right angles from its source.

Due to. the arrangement of the flange connection 2! it is possible torotate the coupling member to a position at right angles to its positionshown in full lines, and when this is done the outlet 23 will be alignedwith the inlet 9, thus producing a passage in direct alignment with theflow of fluid into the valve body. It will be understood that the fluidmay pass in either direction through the valve. Ordinarily it isintended that the inlet shall be directed against the upper side of thevalve, but obviously it may be in either direction.

In Fig. 2 I have shown a valve body I of the same construction as shownin Fig; 1. The coupling member 28, however, is arranged to direct thefluid in a direction axially of the valve stem. This coupling member hasa seat 20 to engage with the seat ring l2 and is connected by the sameflange connection as shown in Fig. 6. This coupling member is threadedat 25 to receive a pipe or other fluid conducting means.

In Fig. 3 I have shown how my valve may be into closed position andsealed on the opposite 10 side of the seat ring. I am thereby enabled toprovide a seal along the line of the valve seat for a materiallyextended period of time before it is necessary to remove the valves sothat the members I! may be reversed, and a new valve seat 15' inserted.It will be obvious that the flow of fluid may be in either directionthrough the compound valve which is thus provided.

I wish to employ my valve in connection with devices in which there maybe pressure against the flow of fluid through the line. This may be usedfor example in feeding water to the boiler of the steam engine. In Figs.4 and 5 I have illustrated how the check valve may be employed in myconstruction.

25 Referring particularly to Fig. 5, the valve body la has a valvebonnet and valve stem' arranged v thereon as in the Fig. 1 embodimentbut the inlet port 9a is directed at right angles to the valve I chamberl9. The outlet port at H! is provided 30 with a recess 20 to receive theseat ring 12. The structure of the valve body is therefore the same asin the previous embodiment withthe exception of the direction at whichthe fluid enters the valve chamber.

35 The coupling member 25 is, however, formed to receive a check valve.I provide a guide sleeve 26 across the interior of the coupling memberto furnish a lateral support for the valve stem 21. Said valve stem hasat its inner end a valve 0 28 similar in construction to the valvemember previously described and adapted to engage with the outer seat l3upon .-the seat ring. The valve is held in position against a head 29 onthe valve stem and the valve is held in its seat by a spring 5 held incompression between the valve and the inner end 3| of thegulde sleeve26. The sleeve is held in position by laterally extending webs 32connected with the inner wall of the coupling member. The outletportfrom the check valve 50 chamber is directed at an angle and is threadedat 33 for connection in the fluid line.

In the operation of this valve the fluid being pumped to the boiler willenter through the port 9a into the valve chamber l9 and will be forcedpast the check valve 28 and out through the port 33 to the boiler. Whenthe pump is stopped the check valve will be held in its seat by thespring but under normal conditions there will be leakage past this valveand in such case I close the valve ll into the valve seat. l3, as in theprevious embodiment. This will force the check valve from its seat but Iwill be able to exert su-flicient pressure upon the manually operatedvalve I 4 to assure a closure until it is necessary to again force fluidpast the valve. I It will be obvious that the check valve may be of anydesired construction. illustrated the same check valve housed within apassage directed at right angles to the opening.

Fig. 4 also illustrates the me of the check valve in any ordinary fluidconducting line. The coupling member 25a in this case forms a valvechamber for the check valve 28 which has the In Fig. 4 I have same typeconstruction as that shown in Fig. 5. The valve stem 21 is supportedwithin a guide sleeve-26 mounted upon webs or arms 3i! connected withthe inner wall'of the coupling. The

'outlet 33a, however, is in direct alignment with 5 the stem 21 of thecheck valve. The valve seat ring I2 is held in position on the end ofthe valve chamber by a connecting member 34 which has a flangedconnection with the coupling member 25a. This connecting member 34 isthreaded at v 35 for connection with the fluid conducting line. Thisconnecting member serves to clamp the valve seat in position and servesas a connection in the fluid line, thus enabling the check valve of myconstruction to be employed not only with the valve but at any positionalong the fluid line.

It will be understood that my valve is adapted for general use and maybe used in various positions and may be arranged in various combinationswhereby the control of the fluid flowing through the line may beassured. A feature of particular advantage in my invention lies in itsflexibility whereby it may be adapted for various uses and may becombined with various forms of coupling members whereby it may directthe fluid flowing therethrough in a direct line or at various anglesrelative to the inlet flow.
